systemd is a software suite that provides an array of system components for Linux [7] operating systems. The main aim is to unify service configuration and behavior across Linux distributions. [8] Its primary component is a "system and service manager" — an init system used to bootstrap user space and manage user processes.

It allows system administrators to deploy and manage Red Hat Enterprise Linux (RHEL) hosts. A Satellite server registers with Red Hat Subscription Management, mirrors all relevant software like security errata and bug fixes, and provides this together with locally added software and configuration to the attached servers.
